*Golden Membranes Pave the Way for a Better Understanding of Cancer and the Immune System*

Football has often been called “a game of inches,” but biology is a game of nanometers, where spatial differences of only a few nanometers can determine the fate of a cell – whether it lives or dies, remains normal or turns cancerous. Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new and better way to study the impact of spatial patterns on living cells.

Berkeley Lab chemist Jay Groves led a study in which artificial membranes made up of a fluid bilayer of lipid molecules were embedded with fixed arrays of gold nanoparticles to control the spacing of proteins and other cellular molecules placed on the membranes. This provided the researchers with an unprecedented opportunity to study how the spatial patterns of chemical and physical properties on membrane surfaces influence the behavior of cells. (more…)

The 1977 discovery of deep-sea hydrothermal vent ecosystems that obtain energy through chemosynthesis rather than photosynthesis greatly expanded the perception of life on Earth. However, an understanding of their underlying microbiology and biogeochemistry still remains elusive. (more…)

RESTON, VA, November 1, 2011 – comScore, Inc., a leader in measuring the digital world, today released a study of audience visitation to public health sites in the U.S. The study found that health-focused sites represented 3 out of the top 10 federal Government sites in September, indicating a high level of public interest in health information. NIH.gov, the flagship property of the National Institutes of Health, drew 10.6 million Americans in September 2011, making it the most popular site in the Government category. (more…)

Babies Understand Thought Process of Others at Ten Months Old, MU Research Finds

COLUMBIA, Mo. – New research from the University of Missouri indicates that at 10 months, babies start to understand another person’s thought process, providing new insights on how humans acquire knowledge and how communication develops.

“Understanding other people is a key factor in successful communication, and humans start to understand this at a very young age,” said Yuyan Luo, associate professor of developmental psychology in the MU College of Arts and Science. “Our study indicates that infants, even before they can verbally communicate, can understand the thought processes of other people – even if the thoughts diverge from what the infants know as truth, a term psychologists call false belief.” (more…)

Black and White American Voters Live in One Country, But Two Different Worlds

The political outlook of blacks in America has undergone dramatic swings in the last ten years — from the depths of powerlessness during the aftermath of Hurricane Katrina, to the zenith with the election of the first black president, Barack Obama.

Now, with another presidential election looming, blacks are again confronting new issues as they judge and sometimes question the impact of Obama’s election, contends UChicago political scientist Michael Dawson, whose work finds sharp contrasts between how African Americans and whites feel about their country.

*In the year since Microsoft launched controller-free Kinect for Xbox 360, the device has taken on a life of its own. First Kinect became the fastest-selling consumer device in history and then it started showing up outside the living room in healthcare, education, and technology.*

REDMOND, Wash. – Oct. 31, 2011 – When it comes to technology and moon landings, there are small steps – and then there are leaps.

It’s been a year since Kinect for Xbox 360 jumped onto the scene, bringing with it a new era of controller-free, interactive gaming and entertainment for the living room.

“It’s been an amazing 12 months – it’s been absolutely inspiring,” says Alex Kipman, general manager of incubation for Microsoft’s Interactive Entertainment Business. “When you have a great vision you expect it to do great things, but it’s humbling and inspiring to actually see it happen and exceed your expectations in terms of the ability – over a very short period of time – that you have affected the entire world.” (more…)
